TL;DR: Results demonstrated varying effects depending on the methodology of the examined study and characteristics of the participants, although overall effects of physical activity on children's mental health were small but significant, indicating that on average physical activity led to improved mental health outcomes for all children.
Abstract: The present study was a comprehensive, quantitative synthesis of the literature examining the effects of physical activity on children's mental health outcomes. The final analysis included 73 published and unpublished studies, totaling 246 effect sizes. Various study and participant characteristics were coded to assess moderator effects, including type of physical activity, mental health outcome, gender, cognitive ability, mental status, and implementer of the physical activity, etc. Results demonstrated varying effects depending on the methodology of the examined study [i.e., correlational vs. randomized controlled trial (RCT)/non-RCT] and characteristics of the participants, although overall effects of physical activity on children's mental health were small but significant, indicating that on average physical activity led to improved mental health outcomes for all children.

TL;DR: It is suggested that multiple-nutrient constraints must be considered when assessing the ecosystem-scale consequences of nutrient enrichment, and significant variations in the type and degree of nutrient limitation are pointed to.
Abstract: Terrestrial ecosystem productivity is widely accepted to be nutrient limited(1). Although nitrogen (N) is deemed a key determinant of aboveground net primary production (ANPP) 2,3, the prevalence of co-limitation by N and phosphorus (P) is increasingly recognized(4-8). However, the extent to which terrestrial productivity is co-limited by nutrients other than N and P has remained unclear. Here, we report results from a standardized factorial nutrient addition experiment, in which we added N, P and potassium (K) combined with a selection of micronutrients (K+mu), alone or in concert, to 42 grassland sites spanning five continents, and monitored ANPP. Nutrient availability limited productivity at 31 of the 42 grassland sites. And pairwise combinations of N, P, and K+mu co-limited ANPP at 29 of the sites. Nitrogen limitation peaked in cool, high latitude sites. Our findings highlight the importance of less studied nutrients, such as K and micronutrients, for grassland productivity, and point to significant variations in the type and degree of nutrient limitation. We suggest that multiple-nutrient constraints must be considered when assessing the ecosystem-scale consequences of nutrient enrichment.

TL;DR: Two different proofs that the flat cover conjecture is true: that is, every module has a flat cover are given, and each has a model‐theoretic flavour.
Abstract: In this paper we give two different proofs that the flat cover conjecture is true: that is, every module has a flat cover. The two proofs are of completely different nature, and, we hope, will have different applications. The first of the two proofs (due to the third author) is essentially an application of the work of P. Eklof and J. Trlifaj (work which is more set-theoretic). The second proof (due to the first two authors) is more direct, and has a model-theoretic flavour.

TL;DR: It is argued that inclusive fitness theory has been of little value in explained the natural world, and that it has led to negligible progress in explaining the evolution of eusociality, but these arguments are based upon a misunderstanding of evolutionary theory and a misrepresentation of the empirical literature.
Abstract: Arising from M. A. Nowak, C. E. Tarnita & E. O. Wilson 466, 1057-1062 (2010); Nowak et al. reply. Nowak et al. argue that inclusive fitness theory has been of little value in explaining the natural world, and that it has led to negligible progress in explaining the evolution of eusociality. However, we believe that their arguments are based upon a misunderstanding of evolutionary theory and a misrepresentation of the empirical literature. We will focus our comments on three general issues.

TL;DR: It is demonstrated that ketones reduce glutamate-induced free radical formation by increasing the NAD+/NADH ratio and enhancing mitochondrial respiration in neocortical neurons, which may contribute to the neuroprotective activity of ketones by restoring normal bioenergetic function in the face of oxidative stress.
